To all 'whom 'it' may concern.

Be it known that I, VERA C. HoDGEs, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Single-Trigger Mechanism, of which the following is a specification.

ln a former patent of mine No. 945,459, January 4th, 1910, I show a single trigger mechanism which may be applied to an ordinary double barrel gun, and the object of the present invention is to provide an improved and simplified construction.

gers which lies within the breech mechanism, is unchanged from the ordinary construction and form. Secured to the under side of the breech mechanism is a frame 6 with a right cover 7 and a left cover 8, as shown in Fig. 3. Arranged within the frame 6 and slidable therein is a slide 9, shown in detail in Fig. 4, and formed with a single trigger 10 at its rear end. Pivoted at 11 to the slide 9 is a trigger' bar 1Q. shown in detail'in Fig. 10, and having a right trigger lug 13 and a left trigger lug 14, which lugs are adapted to be moved against the respective right and left triggers 4 and 5 of the gun and operate the same in a manner to be described. Pivoted at 14 to the trigger bar 12 is an automatic shifter 15 having an upper arm 16 and a lower arm 1G and having a lateral pin 17 which engages in a slot 18 in a manual shifter 19 which is pivoted at 2O to the right cover plate 7 and which has a finger knob 21 projecting through a slot 22 in the plate 7 by means of which the manual shifter 19 may be shifted as desired. Slidable within the automatic shifter 15 is a pin 21 having a circumferential shoulder 29. with a compression spring 23 within the automatic shifter 15 and serving to press the pin 21 outwardly so that its end bears against the bearing face Q4 of the slide 9. Within the slide 9 is a pin 25 with a circumferential shoulder Q6 bearing against a compression spring 27, the spring 27 being confined in the slide 9 by a plug 28. The end of the pin 25 projects into a slot 29 through which a screw or pin 30 passes, the latter preventing rearward movement of the pin 25 so that a rearward movement of slide 9 will compress spring 27, and so that when the single trigger 10 is released the spring 27 will move the slide 9 forward. The slide 9 is also formed wit-h a slot 31 through which extends a screw or pin 32.

Projecting down from the upper side of the frame 6 is an upper post 32. and projecting up from the lower side of the frame 6 is a lower post 33. The right trigger 4 has a notch 34 so that when the trigger bar is in raised position, and is moved rearwardly, its trigger lug 13 will move back into the notch 34 without operating the right trigger 4.

In operation, when the parts stand in the position shown in Fig. 11, the arm 16 of the automatic shifter is in engagement with the upper post 32 and the trigger lug 13 lies below the notch 34 and bears directly against the right trigger 4. Upon pulling back the single trigger 10, the automatic shifter 15 is retracted by means of the pin 14, and as the upper arm 16 is resisted by the post the latter acts as a fulcrum during the rearward motion of the slide and automatic shifter, so that as the trigger bar 12 is moved back its trigger lug 13 presses back the trigger 4 and fires the right barrel, and at the same time the automatic shifter caused to rock upon its pivot 14 so that the pin 21 moves to the lower part of the bearing face 24 which brings the arm 16 under the end of the lower post 33, as shown in Fig. 13, at the conclusion of the rearward stroke of the slide. During this rocking motion of the automatic shifter the pin 21 in pressing down on the bearing face 24 compresses the spring 23 which permits the pin 21 to retract sufciently to permit of this movement. During this movement the left trigger lug 14 in passing rearwardly moves under the lower end of the left trigger 5 and consequently does not operate the trigger 5. This is clearly shown in Fig. 12 wherein the trigger lug 14 is shown at a point below the left trigger 5. After the right barrel has thus been fired, upon releasing the single trigger 10 the spring 27 cxpands and moves the slide forward, and as the slide moves forward it carries the automatic shifter with it and the lower arm 16 thereof moves into engagement with the end of the lower post 33, the parts assuming the position shown in Figs. 15 and 16, and the left trigger lug 14 stands in front of the left trigger 5 by reason of the upward tilting of the trigger bar 12 which occurs during the forward motion of the slide as the parts are moving from the position shown in Fig. 13 to that shown in Fig. 15. With the parts standing as shown in Fig. 15, upon pulling the single trigger 10 back, the left trigger lug 14 acts against the left trigger 5 and operates that trigger, thus firing the left barrel, and at the same time as the lower arm 16 is resisted by the lower post 33 the automatic shifter is caused to be tilted from the position shown in Fig. 15 to that shown in Fig. 17, and upon the release of the single trigger 10 the slide is again moved forward whereupon the upper arm 16 moves into engagement with the upper post 32. It should be understood that with the parts in the position shown in Fig. 13 during the forward motion of the slide the lower arm 16 of the automatic shifter is caused-to move into engagement with the end of the post 33 by a slight upward movement of the trigger bar, and this movement is produced by the reaction of spring 23 within the automatic shifter in which the end of the pin 21 where it bears against the face 24, acts as a fulcrum, and as the pivotal point 14 is above the point of contact of the pin 21 the trigger bar and shifter are moved slight-l y upward the necessary distance to bring the lower arm 16 into engagement with the post 33. lIn like manner the upper arm 16 is moved `into engagement with the upper post 32 as the slide is moved forward from the position shown in Fig. 17 to that shown in Fig. 11, the slight downward movement of the trigger bar and automatic shifter being accomplished by the reaction of the spring 23, the pin 21 at this time lying at the top portion of the bearing face 24. As the trigger bar is thus automatically shifted by the automatic shifter to cause the trigger bar to be alternately moved into coperative engagement with the right trigger and left trigger, the manual shifter 19 is also moved by reason of the engagement of the pin 17 in the slot 18. One advantage of this is that the position of the parts can be ascertained by a glance at the knob 21 which indicates if it is in the lower part of the slot 22 that the right trigger 4 will be ired upon pulling the single trigger 10, while if the knob is in the upper part of slot 22 the left trigger 5 will be operated upon pulling the single trigger 10. The knob 21 may be manually operated to move the manual shifter 19 into either of its two positions and to thereby change the position of the automatic shifter and trigger bar; thus if the parts should stand in the position shown in Fig. 11, and it should be desired to lire the left barrel first, the knob 21 would first be pushed into the upper part of the slot 22, whereupon by pulling the single trigger 10 the left barrel will be fired, and vice versa.

rIhe frame 6 is made in two parts, the part 6a being notched at 6" and 6c to receive tongues 6d and 6e, and pins 6t unite the parts enabling them to be separated to permit the insertion or removal of the single trigger mechanism.
